Gunman. Dicsoarrrron The machine of the instant invention is an accounting machine of the well known Ellis type having a traveling carriage, and if desired, may be equipped with typewriter keyboard and type. This machine is operated by a constantly running electric motor of the type shown in United States Patents to N. W. Perkins, No. 1,136,165, granted April 20, 1915, and to F. W. Bernau, No. 1,301,102,

issued September 28, 1926. The motor is clutched to the machine operating mechanism by the depression of a starting bar, and is automatically disconnected from said operating mechanism near the end of each cycle of operation.

The keyboard is of conventional adding machine form and is composed of a plurality of flexible amount keys arranged in denominational rows. There is also a row of control keys arranged to exercise control over the diflerent functions of the machine.

The machine in the preferred form has a plurality of totalizers arranged in parallel pairs, one above the other, at the rear of the machine. One or more of said totalizers may, if desired, be arranged for both addition and subtraction. The add-subtract totalizers are equipped with a. dual carrying mechanism normally retained in adding position but automatically shifted to subtract position when said totalizers are conditioned for subtract operations. The totalizers are actuated by being engaged with reciprocating racks, which are also adapted to position the accounting machine printing type segments. There is a totalizer wheel, an actuator rack, and a type segment for each denominational row of amount keys. The actuator racks and type segments are positioned for addition and subtraction by depressed amount keys, and in total and sub-total operations they are positioned in the well known I manner by the return to zero of the totalizer wheels.

The machine of the instant invention differs from former Ellis machines in that it is equipped with 'six totaliz ers rather than four, which has heretofore been the maximum. The totalizers are arranged in units consisting of two totalizers mounted one above the other. The units are in turn assembled to each other in such a manner that the three pairs of totalizers are in horizontal alinement.

The totalizers will be numbered as has heretofore been the custom. The upper totalizers beginning nearest the front of the machine will be called No. I, No. 3 and No. 5, respectively. The lower tcalizers beginning nearest the front of the machine will be called, respectively, No. 2, No. 4 and No. 6. All these totalizers are of conventional Ellis construction, the No. .5 and No. 6 totalizers being substantially duplicates of the No. 3 and No. 4 totalizers. There is a common operating means for engaging the No. 3 and No. 5 totalizers with the actuators, which is also the case with the No. 4 and No. 6 totalizers. Selecting means for coupling the desired totalizer to the operating means have been supplied, and are made effective in adding operations by means of stops arranged as desired upon the traveling carriage. In total and sub-total operations the selecting means are made effective by the depression of total keys. In the description to follow the above mechanism pertinent to the instant invention will be treated in detail.

DETAILED DESCRIPTION Totalizer engaging mechanism for adding operations As brought out in the preceding general description, the machine of the present invention has six totalizers arranged in parallel pairs, one above the other (Figs. 4 and 13). These totalize'rs are sequentially numbered, the pair nearest the front being No. I and No. 2, the next pair No. 3 and No. 4, and the last pair No. 5 and No. 6.

Journaled in a pair of main frames 40 and 4| (Figs. 12-A and 12-B) is an operating shaft 42 (Figs. 1,4 and 9) having secured on its lefthand end an operating plate 43. The plate 43 carries a stud 44 upon which is pivoted a flying lever 45 having in its upper end a stud 46. Pivoted on the stud 46 is a pawl 41 urged counterclockwise against a stop stud 48 by a spring 49. The right end of a link 50 is also pivoted on the s ud 46, said link 50 being slotted on its left end to embrace a stud 5I in a crank 52 secured to the left end of a totalizer engaging shaft 53 Journaled in a pair of totalizer frames 54 and 55 (Fig. 12A).

Secured to the shaft 53 (Fig. 13) is a pair of symmetrical cam arms 56, (only one here shown), each having therein a cam slot adapted to cooperate with a pair of rollers 51 mounted on either end of a No. 3 totalizer shaft 58. The shaft 58 has turnably mounted thereon a plurality of totalizer wheels 59 adapted to cooperate with a plurality of actuator racks 60 (one only here shown).

The link 50 (Figs. 1, 4 and 12A) has secured on its left end a hinged latch 6| having a projection 62 adapted to cooperate with the stud 5| in the crank 52 for a purpose to be later delatch M in ineffective position against the head of the screw 63. Secured to the link 50 is a rod 65 (Figs. 2 and 5) having aslot in which is pivoted a latch operating lever 66, one arm of which is formed to cooperate with the latch 6I. The other arm of the lever 66 is pivotally connected by a link 61 (Figs. 1 and 4) to a link I0 pivoted on an arm 'II of a lever I2 pivoted at I3 to the left frame M. The link I0 has an extension I4 which is held against a stop stud I5 in the arm II by a spring I6, thus forming a flexible connection between the arm II and link 61. This flexible connection takes care of any variations of the parts in manufacture, thus insuring proper operation of the parts under all conditions. The righthand arm of the lever I2 is connected by a link 11 to the left arm of a lever 18 (Figs. 3 and 4) pivoted at I9 to a tabulating frame (not shown). The right arm of the lever I8 has an upturned extension adapted to cooperate with a lug 8| on a stop 82 carried by a tabulating bar 83 secured to a traveling carriage (not here shown).

Selection of the No. 3 totalizer for addition is accomplished by tabulating the traveling carriage to a position where the lug 3| (Fig. 3) on the stop 62 will contact the extension 80 of the lever I8, rocking said lever clockwise. This causes the lever I2 (Fig. 1) to rock counter-clockwise, which in turn rocks the lever 66 clockwise (Fig. 2)

thereby moving the latch 6I (Fig. 12A) to a posi- 5 tion where the lug 62 will be in the path of the stud 5| carried by the No. 3 totalizer engaging arm 52.

Referring to Fig. 1, the shaft 42 and the plate 43 are oscillated through an angle of approximately 60 degrees each time the machine is operated, by mechanism not here shown. However, reference may be had to the patents cited at the beginning of this specification for a complete description of this mechanism. The initial clockwise movement of the plate 43 causes the lower end of the pawl 41 to engage a square stud 84 in the plate 43, thereby causing the lug 62 to engage the stud 5| to rock the crank 52, shaft 53 and cam 56 (Fig. 13) counterclockwise to engage the No. 3 totalizer wheels 59 with the actuator racks 60 for an adding operation. The return or counterclockwise movement of the plate 43 causes a stud 85 secured in said plate 43 to engage the lever 45 to lock the crank 52, shaft 53 and cam 56 clockwise to disengage the totalizer wheels from the actuator racks 60 near the end of the operation of the machine.

Pivoted on the link 50 (Fig. 1) is another link 86 having a slot through which extends a stud l 81 in a crank 90 secured to a No. 5 totalizer engaging shaft 9I journaled in a pair of totalizer frames 92 and 93 (Figs. 1 and 12B). Secured to the rear end of the link 86 is a hinged latch 94 similar to the latch BI, and having a lug 95 adapted to cooperate with the stud 81. A screw 96 threaded in the link 86 extends through a clearance hole in the latch 94. A compression spring 91 coiled around the screw 96 holds the latch 94 in ineffective position against the head of the screw 96. I

Secured to the link 86 is a rod 98 having a slot in which is pivoted a lever 99, one arm of which is formed to cooperate with the latch 94. The other arm of the lever 99 is pivotally connected by a link I00 to a crank IIlI (Figs. 1 and 12B) fast on a shaft I02 journaled in the totalizer frames 92 and 93. Secured to the shaft I02 is an arm I03 pivotally connected to a flexible link I04 composed of bars I05 and I06 flexibly coupled to each other by means of a spring I01. The bar I06 (Figs. 1 and 6) is pivoted to a lever I06 pivoted at I09 to the right frame 40. A bar H is also pivoted tothe lever I06 (Figs. 1 and 12B) and has its forward end formed and threaded to receive an adjustable screw pin III secured by a nut H2. The pin III extends through a hole in a tabulating frame I I3, and is adapted to cooperate with a No. totalizer adding stop II4 (Figs. 1 and 3) carried by the stop bar 63.

To select the No. 5 totalizer for addition it is necessary to tabulate the traveling carriage to a position where the stop II4 (Figs. 1 and 3) will engage the pin III, forcing it and the bar IIII toward the rear of the machine, to rock the lever I 06' counter-clockwise, which, through the link I04, rocks the arm I03, shaft I02 and crank IOI clockwise, whereupon link I00 rocks the lever 96, which moves the latch 94 to a position where the lug 95 will be in the path of the stud 61. Initial movement clockwise of the shaft 42 (Fig. 1) and plate 43, as explained above, moves the link 66 toward the front of the machine, causing the lug 95 to contact the stud 61 and rock the crank 90 and engaging shaft 9'I counter-clockwise, whereupon cam arms 69 (Fig. lit-only one arm being shown) fixed to the shaft 9I rock the No. 5 totalizer wheels 59 into engagement. with the actuator racks 60 to add in the No. 5 totalizer. The return counter-clockwise movement of the shaft 42 and'plate 43 causes the totalizer wheels to be disengaged from the actuator racks near the end of the machine operation.

The mechanisms for engaging the No. 4 and No. 6 totalizers with the actuators in adding operations is substantially a duplicate of and operates in exactly the same manner as the No. 3 and No. 5 engaging mechanisms, respectively, explained above.

In Fig. 3 is shown a hanging bar lever I53 associated with the No. 4 totalizer. To this lever I53 is connected ,a link I41 (Figs. 1, 4, 12A and 123), which is in turn connected to a lever I12. This lever I12 is connected by a flexibly mounted bar I49 to a link I13 attached to a lever I14 which cooperates with a latch I66 on a link I60. The latch I66 has a projection I69 arranged to cooperate with a stud I6I in a crank I62 secured to a shaft I63. The link I60 ispivoted on a stud I56 on a flying lever I55 mounted at I54 on the plate 43. This lever I55 is common to both the No. 4 and No. 6 totalizers. Pivoted on the lever I55 is a pawl I51 normally urged counter-clockwise against a stop stud I56 by a spring I59. A stud I46 on the operating lever 43 is adapted to cooperate with the lower end of the pawl I51, as the lever 43 rocks clockwise. When the stud I46 reaches the pawl I51, continued movement of the lever 43 causes said stud I46 to effect a forward movement of the upper end of the flying lever I55 to draw the link I60 forwardly in the usual and well known manner, as set forth in the previously mentioned Ellis patents.

The latch I66 is similar to the latch 6|, and when the lever I53 (Fig. 3) is operated by a stop 62, the parts I41, I12, I49, I13 and I14 (Fig. 1) actuate the latch I66 to move its projection I69 into the path of the stud I61. Therefore, when the link I60 is moved towards the front of the machine upon operation of the driving plate I43, the crank I62, shaft I63 and cam arms I46 (Fig. 13) fixed to said shaft (only one arm being shown), engage the No. 4 totalizer with and disengage it from the racks 60.

For engaging the No. 6 totalizer during adding operations there is provided a screw pin 300 Figs.

3 and 12B) mounted like the pin III and adapted It; belepressed by any stop I I4 on the tabulating The pin 300 is carried by a bar 30I (Fig. 128) pivoted to a lever 302 (Fig. 12A) mounted in axial alinement with the lever I06. Also connected to the lever 362 is a flexible link 303 consisting of bars 304 and 305 and a spring 306. The bar 305 (Figs. 1 and 12A) is connected to an arm 301 fixed to a shaft 306 mounted in the frames 92 and 93. Also secured to the shaft 306 is an arm 309 connected by a link 3I0 to a lever -3II pivoted in a stud 3I2 carried by a link I64 connected to the previously described link I60.

The link I64 (Fig. l) is slotted at its rear end to receive a stud I65 in a crank. I66 secured to a No. 6 totalizer engaging shaft I61 journaled in the frames 62 and 93, and having fixed thereto cam arms I19 (Fig. 13only one arm being shown). The link I64 carries a hinged latch I10 which has a projection I1I arranged to cooperate with the stud I65 in the crank I 66. The latch I10 is similar to the latch 94, explained above, and in adding operations when one of the stops II4 presses the pin 300 inwardly, or towards the rear of the machine, the train of mechanism conslst ing of the parts 30I to 3I2 forces the latch I10 towards the link I64 (Fig. 4) and places the projection I1 I in the path of the stud I65. Now when the operating plate 43 is oscillated, the flying lever I55, through the pawl I51, links I60 and I64, and latch I10, oscillates the crank I66 and shaft I61, whereupon cam arms I19 (Fig. 13-only one arm being shown) engages the No. 6 totalizer with and disengages it from the racks 60.

Engam'na mechanism for the N0. 3 and No. 4 totalizers in total operations Calling attention to Fig. 4, a No. 3 total key I I5 has therein a notch I I6 adapted to cooperate with a lug II1 on a latch I20 pivoted at I2I to the let. frame H. The latch I20 has in its lower end :1. stud I22 adapted to cooperate with a total cam I23 pivoted on a stud I24 extending between the left frame H and a sub-frame II9 (Fig. 12B). Also pivoted on the stud I24 (Fig. 4) and operatively connected to the total cam I23 is a total cam lever I25 having pivoted thereon a pair of pawls I26 and I21 arranged to cooperate with the lower end of the flying lever 45, for a purpose to be described later. The key I I5 also has another notch I26 arranged'to cooperate with a projection I29 formed on the forward end of a lever I30 pivoted on a stud I3I carried by the left frame H. The rear end of the lever I30 is connected by a rod I32 to the lever 16.

Depression of the No. 3 total key II5 (Fig. 4) through the notch I26 and projection I29 rocks the lever I30 clockwise. The rod I32 coacting with the lever 16 rocks the lever 12 counterclockwise to move the lug 62 on the latch 6| into the path of the stud 5I in the crank 52. Depression of the No. 3 total key II5 also moves the notch II6 opposite the lug II1, allowing the latch I20 to be forced clockwise by a spring I48. This causes the stud I22 to engage the cam I23, rocking it and the lever I25 clockwise to move the pawls I26 and I21 into the path of the flying lever 45. Therefore, oscillation of the plate 43 during machine operations, as explained above, through the medium of link 50, latch GI, crank 52, shaft 53 and cam arms 56, causes the No. 3 totalizer (Fig. 13) to be properly engaged with and disengagedfrom the racks 60 during a total taking operation.

Referring to Figs. 4 and 6, a No. 4 total key I33 has a notch I34 arranged to receive a lug I35 on a latch I36 pivoted to the left frame 4 I. The latch I35 is connected by a link I 31 to a lever I 38 pivoted at I39 to the left frame. The lower end of the lever I38 carries a stud I40 which cooperates with a total cam I4I pivoted on a stud I42 extending between the frames 4| and H9. Pivoted on the stud I42 and operatively connected to the total cam MI is a total cam lever I43 which carries a pawl I44. The left end of the lever I43 and the pawl I44 are adapted to cooperate with the lower end of the flying'lever I55 for the No. 4'

Depression of the No. 4 total key I33 (Figs. 4,

12A and 123) through the stud I50, lever I5I, rod I52, lever I53, lever I12, and link I13 rocks the lever I14, whereupon the latter moves the latch I68 so that the projection I69 (Fig. 4) thereon will be in the patch of the stud I6I in the engaging crank I62. Depression of the total key I33 (Figs. 4 and 6) also allows the lever I38 to be rocked clockwise by a spring I15, which also rocks the lever I43 and pawl I44 clockwise into the path of the flying lever I55. Thus, oscillation of the operating plate 43 during the machine operation, through the medium of the link I60, latch I68, crank I62, shaft I63 and cam arms I48, causes the No. 4 totalizer to be properly engaged with and disengaged from the actuator racks 60 for a total operation.

Engaging mechanism for the No. 5 and No. 6 to talizers in total operations An angle plate I16 (Figs. 7 and 12B) secured to the right frame 40 carries a No. 5 total key I11 and a N0. 6 total key I18. The total key I11 has a stud I which cooperates with an extension on a lever IOI pivoted on a stud I82 in the plate I16. The upper end of the lever I8I is connected by a link I83 to the lower end of lever I84 pivoted on a stud I85 secured in a right-hand printer frame I19. The upper end of the lever I84 is adapted to cooperate with a stud I86 in the bar Hi] to select the No. 5 totalizer for a totalizing operation.

The lower end of the No. 5 total key I11 (Figs. '7 and 10) is arranged to cooperate with an extension of an arm I81 secured to the right-hand end of a sleeve I88 carried by a shaft I90 journaled in the main frames 40 and M (Figs. 12A and 12B). Secured to the left-hand end of the sleeve I88 (Figs. 9 and 10) is a forked arm I9I, the tines I92 and I93 of which carry, respectively, studs I94 and I95. The studs I94 and I95 embrace an arm I96 pivoted at I91 to the frame 4|. The lower end of the arm I96 carries a stud 200 arranged to cooperate with the previously described total cam I23 for a purpose to be later described. A spring I98 normally holds the parts in the positions shown.

' Depression of the N0. 5 total key I11 (Figs. '1 and 123), through the stud I80, lever I8I, link I83 and lover I84, forces the bar IEO toward the rear of the machine. This rocks the lever I08 counter-clockwise, which, through the link I 04 (Fig. 1), arm I03, shaft I02, link I09 and lever 99, moves the latch 94 inwardly so that the lug 95 will'be in the path of the stud 81 in the No. 0 engaging crank 90.

Depression of the No. 5 total key I11 (Figs. 7 and 9) also rocks the arm I 81, sleeve I88 and forked arm I9I counter-clockwise. This causes the studs I94 and I95 to rock the arm I98 clockwise, whereupon the stud 200 rocks the total cam I23 clockwise. This moves the usual pawls I26 and I21 (Fig. 4) into the path of the flying lever 45.

With the lug 95 (Fig. 1) in the path of the stud 81, and with the pawls I26 and I 21 in the path of the flying lever 45, upon clockwise movement of the operating plate 43, the links 50 and 86 are immediately drawn forwardly, thus rocking the crank 90, shaft 9I, and cam arm 89 (Fig. 13) counter-clockwise, which meshes the No. 5 totalizer wheels 59 with the racks 60 for totalizing purposes.

After the No. 5 totalizer is cleared the lever 43 is returned home, during which time the pawl I21 causes the flying lever 45 to return the links 50 and 86 to normal to disengage the totalizer from the racks 60. Upon restoration of the key I11 by means later described, the spring I99 restores the parts I81, I88, I9I and I96 to normal.

The No. 6 total key I18 carries a stud 280 (Figs. '7 and 12B) cooperating with a lever 28I pivoted on a stud 282 in the plate I16. The lever 28I is connected by a link 283 to a lever 284, like the lever I84, and shown only in Fig. 12B. The lever 284 is pivoted on the stud I85, and its upper end cooperates with a pin 286 in the bar 30I.

The lower end of the No. 6 total key I18 (Figs. '1, 9 and 10) is arranged to cooperate with an extension of an arm 20I secured to the right-hand end of the shaft I90. Fast on the left end of the shaft I90 is a lever 202 having an arm 203 connected by a link 204 to an arm 205 pivoted at 206 to the left frame 4|. A spring I99 holds the parts associated with the lever 20I normally in the positions shown in Figs. 7, 9, and 10. The arm 205 carries a stud 201 which is arranged to coact with the total cam I4I for a purpose to be hereinafter described. The lever 202 has an arm 201 arranged to engage a stud 208 in a usual repeat key release lever 2I8 (Fig. 11) to release the usual repeat key (not shown herein).

Depression of the No. 6 total key I18 (Figs. 7 and 12B) through the stud 280 lever 28 I, link 283, and lever 284, forces the bar 30I towards the rear of the machine, which, through the lever 302, link 303 (Fig. 12A), arm 301 (Fig. 1), shaft 308, arm 309, link 3I0 and lever 3I I, moves the latch I10 and places its projection I1I into the path of the stud I65 on the No. 6 totalizer engaging crank I66.

Depression of the No. 6 total key I18 (Figs. '1 and 9) also rocks the arm 20I, shaft I90 and lever 202 counter-clockwise, which, through the link 204 rocks the arm 205 clockwise. This causes the stud 201 in the arm 205 to engage and rock the No. 6 total cam I M clockwise, moving the lever I43 and the pawl I44 (Fig. 4) into the path of the flying lever I55.

With the projection I1I (Fig. 1) in the path of the stud I65, and with the lever I43 and pawl I44 in the path of the flying lever I55, the clockwise movement of the operating lever 43 will draw the links I60 and I64 forwardly, thereby rocking the crank I66, shaft I61 and cam arm I19 (Fig. 13) clockwise to engage the No. 6 totalizer. wheels with the racks 60 for totalizing purposes.

Restoration of the lever 43 reverses the movements of the links I66 and I64, thus disengaging the totalizer from the racks.

Total keu releasing means In the instant machine the means for releasing the Nos. I, 2, 3, and 4 total keys in total and subtotal operations is similar to that of former Ellis machines shown in the previously mentioned patents. However, newmechanism has been devised for releasing the Nos. 5 and 6 total keys I11 and I16, which means is operatively connected to the usual releasing means referred to above.

In the description to follow the new releasing mechanism and as much of the conventional releasing mechanism as is necessary, will be described.

Referring to Figs. 7 and 8, the studs I32 and 262 carried by the plate I16 have pivoted thereon a pair of latches 2I6 and 2I I, each of which has a lug 2I2 adapted to cooperate with notches 2I3 and 2I4 in the total keys I11 and I13. The lugs 2I2 are also arranged to be engaged by projections 2I5 and 2I6 respectively, on a release bar 2I1, slidably mounted on the plate I16. The bar I 2" has pivotally connected thereto an arm 226 secured to a shaft 22I journaled in the frames 46 and 4I (Fig. 123). Secured to the left end of the shaft 22I (Fig. 9) is an arm 222 having therein a hole through which extends a stud 223 fast in a usual total release bar 224. Directly back of the total release bar 224 is a usual subtotal release bar 225 reciprocably mounted at its rear end on a stud 226 in a sub-total release lever 221 pivoted to the left frame 4I, and at its front end on a stud 226 fast in an arm 229 also pivoted to the frame H. The total release bar 224 is likewise reciprocably mounted by having therein a slot which embraces the stud 226 in the lever 221 and another slot which embraces the stud 226 in the arm 229.

The total release bar 224 has pivoted thereon a lever 236 held in a neutral position by a spring 23I. The upper end of the lever 236 is notched to cooperate with a stud 232 carried by the frame H. The lower end of said lever 236 is arranged to cooperate with a stud 233 in an operating plate 234 secured to the shaft 42.

I The operating plates 234 and 43 are symmetrical in outline and function in exactly the same manner. The plate 234 has therein two studs 235 and 236, having respectively pivoted thereon two flying levers 231 and 236, which operate to engage the No. I and No. 2-totalizers with the actuator racks 66 in the usual and well known manner.

The stud 235 extends through the plate 234 and is arranged to engage the lower end of the subtotal release lever 221. The total release bar 224 has a plurality of projections 239 (Figs. 6 and 9),

one of which projections is arranged to cooperate with the lug II1 on the Nos. 3 and 5 latch I26, and another to cooperate with the lug I35 on the No. 4 and No. 6 latch I36. The release bar 224 (Fig. 9) carries a stud 246 and the release bar 225 carries a stud 24I, both of which are adapted to cooperate with .a wedge 242 pivoted on a sub-total key243. A weak spring 244 is tensioned to urge the release bar 224 toward the rear of the machine in order to hold the projections 239 in contact with the lugs H1 and I35.

As the operating plate 234 (Fig. 9) makes its initial movement clockwise in total operations, the stud 233 wipes past the lower end of the lever 236. The return movement counter-clockwise ofthe plate 234 causes the stud 233 to engage the lever 236, forcing its upper end against the stud 232 to move the release bar- 224 toward the rear of the machine. This causes the projections 239 on said bar 224 to rock the latches I26 and I36 counter-clockwise to release either the No. 3 or No. 4 total keys, depending upon which one had been previously depressed. Upon being released, the depressed No. 3 or No. 4 total key is returned upward to normal position by means of compression springs (not here shown).

The rearward movement of the bar 225 rocks the arm 222, shaft HI and arm 226 (Fig. '1) counter-clockwise, moving the release bar 2I1 rearwardly, causing the projections 2I5 and 2I6 (Fig. 8) to engage the lugs 2I2, rocking the latches 2I and 2H counter-clockwise to release either the No. 5 or No. 6 total key I11 or I16, depending upon which one had been previously depressed. A compression spring 249 then returns said key upward to its normal position.

In total operations the totalizer wheels are disengaged from the actuators as soon as they have been returned to zero. This is accomplished by means of the pawls I21 and I44 (Fig. 4) engaging their respective flying levers 45 and I55 on the return movement of the operating plate 43. In sub-total operations initial movement of the plate 43 releases the depressed total key, lowering the pawls I21 and I44 out of the path of their respective flying levers 45 and I55, thus retaining the totalizer wheels in mesh with the actuator racks 66, which causes said totalizer wheels to be returned to their original condition prior to such sub-total operation.

A sub-total operation is effected by depressing the sub-total key 243 (Fig. 9) in conjunction with the total key of the totalizer which it is desired to sub-totalize. Depression of the sub-total key 243 forces the wedge 242 between the studs 246 and '2 in the release bars 224 and 225. Initial movement clockwise of the plate 234 causes the extended end of the stud 235 to engage the lever 221 to rock the release bar 225 rearward, which, through the wedge 242, studs 246 and 2, causes the release bar 224 to move in unison therewith, thus releasing the depressed total key and the sub-total key. This lowers the pawls I21 and I44 out of the path of their respective flying levers 45 and I55, allowing the wheels of the selected totalizer to remain in mesh with actuator racks 66 until they are restored to their original condition.

Modified form Fig. 14 illustrates a modified form of totalizer selecting mechanism for the No. 5 and No. 6 totalizers in whic the total keys are mounted on the left side 'of the keyboard. All of the mechanism not illustrated is similar to that of the preferred form, which was treated somewhat at length hereinbefore. The modified form of total key arrangement will now be explained.

Mounted just inside the left frame 4I (Fig. 14) is a No. 5 total key 245 and a No. 6 total key 246. These keys are connected to the totalizer engaging mechanism by mechanism similar to that of the preferred form described above; therefore, it is felt unnecessary to again illustrate or describe this mechanism. The No. 5 total key 245 carries a stud 241 arranged to cooperate with an arm 256 secured to a sleeve 25I turnably mounted on a shaft 252 journaled in the frames 46 and H. Secured on the right-hand end of the sleeve 25I is an arm 253 connected by a link 254 to a lever 255 pivoted on a stud 256 carried by the right frame 46. The lever 255 is connected by a link 251 to another lever 256 pivoted on a stud 269 fast in the right printer frame I19. The upper end of the lever 268 ccoperates with the stud I86 in the bar llll (Figs. 1 and 7)-. From this point on the mechanism is identical to that of the preferred form, with the following exception.

In the modified form the bar H and connecting mechanisms for the N0. 'totalizer selecting latch mechanism hav e been switched with the No. 6 mechanism, so that the No. 6 mechanism is on the extreme right and the No. 5 mechanism is just to its left.

Depression of the No. 5 key 245 rocks the arm 250, sleeve 25l, and arm 253 clockwise, which through the link 254, lever 255, link 251 and lever 258, forces the bar H6 toward the rear of the machine. This moves the latch 94 (Fig. 1) to its effective position where the lug 95 is in the path of the stud 81 carried by the No. 5 engaging crank 96. whereupon oscillation of the plate 43 efiects the engagement and disengagement of the No. 5 totalizer, with and from the racks 60, in the manner previously described.

The No. 6 ,total key 246 (Fig. 14) carries a stud 26l, which. cooperates with a finger 262 of a Y- shaped arm 263 pivoted to a slotted stud 264 carried by a usual front rack bar 265 rigidly mounted between the frames 46 and 4 I. Another finger 266 of the arm 263 has therein a stud 261 arranged to cooperate with another stud 268 secured in the shaft 252 and extending through an opening 269 in the sleeve 25I. The right end of the shaft 252 carries an arm 210 connected by a link 21! to a lever ,212 pivoted on the stud'256. A link 213 connects the lever 212 to another lever 214 pivoted on the stud 259. The upper end of the lever 214 cooperates with the stud 286 on the bar 30! associated with the No. 6 totalize'r selecting latch mechanism previously described.

Depression of the No. 6 total key 246 (Fig. 14) through the stud 26l, the Y-shaped arm 263, stud 261 and the stud 268, rocks the shaft 258 and arm 210 clockwise, which through the link 21!, lever 212, link 213 and lever 214, forces the bar 361 and its associated No. 6 totalizer selecting mechanism rearward, moving the latch 110 (Fig. l) to effective position where the lug I1! isin the path of the stud I65 in the engaging crank I66. Oscillation of the plate 43 during machine operation then causes the selected No. 6 totalizer to be properly engaged with and disengaged from the actuator rack 60 in the same manner as herein before set out.

In summarizing briefly it will be seen: That two totalizers have been added to the instant machine, making in all six totalizers; that the No. 3 and No. 6 totalizers are engaged with the actuators by a common engaging mechanism which is likewise trueof the No. 4 and No. 6 totalizers; that each of the totalizers, Nos. 3, 4, 6 and 6, is equipped with a selecting latch mechanism operated for addition by stops arranged on the traveling carriage and operated by means of keys lnr total and sub-total operations.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
